ROTOR WITH INTEGRATED DESIGN OF BLADE SET Russian patent published in 2004 - IPC

Abstract RU 2221922 C2

FIELD: mechanical engineering; power plant engines. SUBSTANCE: proposed rotor with integrated design of set of blades arranged over perimeter and passing mainly in radial direction is designed for use in engines of power plants. Rotor blades are provided with metal shank, metal section of airfoil portion and airfoil portion made of plastic reinforced by fiber. Metal section of airfoil portion forms part of blades leading edge beginning radially inside at blades shank and terminating at a distance from radially outer end of blade leading edge and part of blade surface adjacent to edge. EFFECT: reduced vibrations in process of operation, increased plasticity of blade, prevention of erosive wear, provision of minimum weight of blades. 8 cl, 3 dwg
